Samir Nasri London - Arabstoday   The transfer could be finalised in the next 24 hours, with City paying Arsenal a reported £25m. Nasri, who joined the Gunners from Marseille in 2008, is into the final 12 months of his contract and has rejected a new deal at the Emirates Stadium. The France midfielder, 24, would become the second high-profile departure from Arsenal this week after Cesc Fabregas joined Barcelona on Monday. Nasri used social networking site Twitter to congratulate Fabregas on his move and criticise Gunners fans who directed an abusive chant towards him during Saturdays 0-0 draw at Newcastle. "I heard what the fans were singing about me on Saturday and it is really disrespectful because I'm still a [sic] Arsenal player", he wrote. There were suggestions Nasri would undergo a medical on Wednesday - and camera crews gathered at the Bridgewater Hospital. But that was never likely because the clubs were - and are still are - in negotiations and no medical can take place until a deal is agreed. Arsenal began discussions with Nasri in December 2010 but the Frenchman is understood to have stalled on a new three-year contract worth £90,000 a week - and in June he cast further doubt over his future.The Gunners reportedly turned down a £20m bid from from Manchester United in early July and manager Arsenal Wenger said he was prepared to lose Nasri on a free transfer next summer rather than sell him now. "Imagine the worst situation - we lose Fabregas and Nasri," stated Wenger. "You cannot convince people you are ambitious after that. You cannot pretend you are a big club. "A big club holds onto its big players and gives a message out to all the other big clubs that they just cannot come in and take [players] away from you." City boss Roberto Mancini then made clear his intention to bring Nasri to Eastlands and although Wenger claimed on Monday that the player may yet stay, the situation has since developed. If the deal goes through Nasri will receive a huge pay rise and become Mancini's third major summer signing following the arrivals of Gael Clichy, Stefan Savic and Sergio Aguero. Nasri has scored 27 goals in 124 appearances for Arsenal and has won 23 caps for France.
